COIN OPERATED INDUCTION COlL.

EPECIPICATION forming part of Letters Patent No. 385,927, dated July 10 1888.

(No model.)

To all whom, it may concern:

Be it known that I, Josnrn \Vn. HAZELL, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Coin-Operated Indiictioii-Ooils,of which the following is a specification.

My invention relates to an apparatus for administering aseries of electric shocks for therapeutic or experimental purposes.

The invention has for its object to provide mechanism so combined with an inductioncoil and a battery or batteries that the circuit will remain normally broken or in an inoperative condition, and will be established by de positing a coin and moving a circuit-closer.

Apparatus have been heretofore constructed in which coins dropped into a conductor are arrested before reaching the receptacle in such manner that they serve in some cases as a portion of a circuit completed by and through them, and in other cases to close and hold an electric switch in the primary circuit of an indnctioircoil, the release of the coin being finally effected after the operation of the apparatus by various contrivances designed for the purpose.

My invention comprehends a system in which the complicated mechanisms for arresting and relcasi ng the coin are wholly dispensed with, and the coin permitted while pursuing its forward course to act upon and close a switch, which remains closed without further action or assistance on the part of the coin. It also contemplates the closing of the circuit and the bringing of the coil into action by a manual device independent of the electrodes or handles, both of which are made stationary.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a front elevation of the apparatus. A portion of the cascfront is broken away near the bottom to expose certain parts to view. Fig. 2 is a vertical section on the line 2 2, being a view of the interior parts seen by removal of one side of the case. Fig. 3 is a horizontal section on the line 3 3. Fig. at

is a vertical section on the line 4 4, Fig. 2, showing a rear view of certain parts looking toward the front. Fig. 5 is a view ofthe roller, its pulley, and the cords connected therewith.

Fig. 6 is a diagram illustrating the circuitwires connecting the parts.

The letter A designates the case which in closes the apparatus; 3, a bar permanently secured on the front of the case. The center of this bar is wood, or some poor conductor, while the two ends a are metal and are in electric connection by means of the wires a with the induction-coil, and constitute the positive and negative electrodes. Two battery cells, C O, in the present instance, and an induction-coil, D, are employed, which are connected together through the mechanism hereinafter described in detail.

The apparatus may be worked with one battery.

The handle-electrodes a are brought into the circuit by the circuit-closing lever E and circuit-closer bar F. The circuit-closing lever E is actuated by depositing a coin-such as a United States nickel five-cent piece-in the slit-opening b in the wall of the case, from which a chute, I), inclines to a receptacle, 1), for the coins. The circuit-closer bar F projects through the wall of the case and on the outside has a handle, F, and thereby the hand of the person who is to receive the shock may move the said bar endwise. This bar, besides closing the circuit, regulates the intensity of the electric current and raises and lowers the reservoir, as hereinafter explained. In the present instance the said bar F is moved horizontally by being pulled out by the persons hand. When released, it retracts automatically by the action of aweight, c, and a cord, (1, which connects the bar and weight. The cord from its point of connection with the bar F passes in a nearly horizontal direction to the roller 0, once around said roller, and then vertically down to the weight 0, which occupies and moves up and down in a vertical cylinder, 1''. This cylinder may contain air or some fluidsuch as oilthrough which the weight may move, the oil serving to check and prevent the too sudden descent of the weight, and thereby secure the operation of the parts with moderatespeed and without concussion. The circuit-closing bar F has a pin, 2', projecting from one side.

A wire, 9, passes from one cell of the bat tery G to the primary wire of the inductioncoil D. Another wire, 9, leads from the said' nection is provided between the second plate,

G, and the said pin 2'. This connection embracesa spring-plate, j, fastened at one end rigidly by pins and free at the other end. The free end projects across the circuit-closing bar F, and is in position to be pressed by the pin t when the said bar Fis moved endwise in one directionforinstance,when pulled out by the handle F. Awire, g, connects the springplatej with the second plate, G, of the commutator. The circuit-closing lever E is made of non-conducting material and is suitably pivoted at it. One end is provided with a metallic plate, Z, which comes in contact with both the first and second plates, G G, of the cireuitcloser, and there establishes electric connection. Tfie other end of the circuit closing lever projects immediately over the chute b. The top of the chute is open and the end of the switch-lever is in position to be struck by a coin that passes down the chute. The coin deposited in the opening b will thus shift the lever E from the position shown in Fig. 3 and cause its end plate, Z, to make the connection, as described, between the two conducting-plates.

From the foregoiugit will be seen that normally the battery-circuit, which includes the primary wire of the induction-coil, is broken at two points-first, between the plates G G,

and, second, between the pin 71 and plate j.

. When t-he apparatus is to be used, a coin is first deposited in the opening I and in descending therethrough by gravity toward the receptacle 1) its upper exposed edge encoun ters the lever E with sufficient momentum to move the lever backward out of its path, thereby causing the plate Z at the opposite end of the lever to close the circuit between the plates G G. The coin continues its course without interruption past the lever to the receptacle, the circuit remaining closed without further assistance from or dependence upon thecoin. After the circuit has been thus closed atthe first point, the bar F is drawn outward In order to retain the circuitclosing lever E in that positionlwhere its end plate, Z, establishes connection between the two plates of the commutator, a permanent magnet, H, is employed to hold the lever. This magnet is fixed to a suitable support, m, and the wood switch-lever has on one side a metal plate, it, on which the said magnet acts. When acoin shifts the circuit-closing lever E,the metal plate a will come in contact with the magnet H, which will hold it so that its end plate, I, will remain in connection with the said two plates G G.

To automatically effect the release of the circuit-closing lever E from the magnet and effect the reopening of the circuit between-the plates G G, a trip-arm I, is provided asshown in Figs. 2 and 3. This arm is supported by a pivot, o, and has a vertical position at one side of the magnet. The arm I tilts in a vertical plane. Below the. pivot the arm has a point, p, which engages with teeth 1) on the side of the circuit-closing bar F. The arm also has below the pivot a weight, g, which keeps the arm upright. The teeth 19 on the bar have one side slanting and the other side vertical, from which it results that in pulling out the circuit-closing bar F the teeth 19 will slip past the said point pon the arm; but'when the weight and cord 61 move said bar F inward (or retract it) the teeth will so engage said point on the lower part of the arm as to tilt the arm and cause the upper part to move ,forward, and thereby push the lever E away or'relrase it from the magnet H and moveit to that position where, as before stated, it will be struck by a coin passing down the chute.

The roller e, over which the weight-cord d passes has two pulleysa small one, 1, and a larger one, s. A cord, r, made fast to the small pulley connects with the movable central core, 15, of the induction-coil D. The core consists of a bundle of wires or a rod of soft iron-such as is commonly used in connection 'with induction-coils-to vary the strength of the inducing-current. It will thus be seen that when the bar F is pulled out (more or less) the roller 9 will be correspondingly turned or partly turned, and the said cord T will raise or remove the movable section t of the induction-coil D, the power of which is thereby increased. The drawing out of the bar F therefore (more or less) regulates the intensity of the electric current, and the person whose hands are on the electrodes may receive a current of greater or less intensity, according to the extent of movement given to the bar F.

I employ a graduated glass tube, L, a reservoir, L, to contain liquid, and a flexible tube, a, connecting the said glass tube and reser- IIO voir, for the purpose of indicating the strength the reservoir L and glass tube L will maintain the same level at the ends of the two columns-that is to say, the liquid will rise in the glass tube to the same height that it has in the reservoir. When the reservoir is raised, the liquid will rise in the tube, and vice versa.

From the foregoing it will be understood that as the barF is pulled out. (more or less) the roller e will be turned, the electric currentintensified, and the liquid're-servoir elevated correspondingly, whereupon the position of the liquid in the glass tube L will indicate the strength of the current.

The description above given will make plain that the apparatus will give the electric shock or current only after a coin has been deposited in it, as specified, and that after each use by one person the apparatus will automatically break circuit and resume its normal inoperative condition.

While I prefer to retain the details of construction herein shown, it is manifest that they may be modified within the range of mechair ieal skill provided a mode of operation substantiallysuch as herein described is retained. One of the essential features of my invention resides in the arrangement of the circuit-clos ing device in such manner as to be operated by a coin passing thereby without stoppage of the coin, and obviously the precise form of apparatus herein shown is not essential to this action.
